HOSE-CLAMP.

Specification of Letters Patent.

Patented April 30, 1907.

Application filed January 30, 1906. Serial No. 298,715.

and ABRAHAM L. TAYLOR, citizens of the United States, residing at IIarrisburg, in the county 01 Dauphin and State of Pennsylvania, have invented new and useful Improvements in I-Iose-Clamps, of which the following is a specification.

This invention relates to hose clamps, the object of the invention being to provide a simple, convenient and reliable hose-clamp in which special provision is made [or obtaining a firm bearing and clamping action ontlrely around the hose where the latter lits over the pipe orlnozzle to which it is connected.

Viththe above general object in view, the invention consists in the novel construction, combination and arrangement ol parts, as hereinafter fully described and claimed.

In the accompanying drawings, Figure l. is a plan View of a hose clamp embodying the present invention. Fig. 2 is a side elevation of the same. Fig. 3 is a longitudinal section through the clamp extending transversely through the overlapping portions of the hose and pipe or nozzle to which it is coi'mected. Fig. 4 is a detail perspective view of the spring clip.

Like reference numerals designate corresponding parts in all the figures of the drawings.

The hose clamp contemplated in this invention comprises two substantially similar members 1 and 2, the central or body portion of which is substantially semi-circular, as best illustrated in' Fig. 3, so as to extend somewhat less than half way around the joint. Each member also comprises oppositely extending wings 3 which project lrom opposite sides of the semicircular body portion. The wings of each clamping member lie opposite each other and are provided with holes for the reception of clamping bolts 4 which pass through the wings and receive clamping nuts 5, whereby the clamping members may be confined with any desired pressure around the joint.

In connection with one of the members, a s ring metal clip 6 is employ ed. This clip is escribed on an are somewhat in excess of a semi-circle, so as to embrace the joint a little more than one halfway around the hose, and the extremities of the clip are bent inward, as shown at 7, so as to engage and retain the hose where the latter is slipped over the pipe of the nozzle, 8 designating a section 0f the hose, and 9 a metal pipe or nozzle, over the end oiwhich the hose 8 is slipped preparatory to applying thereto the clamp. The oppo site portions or arms ll) of the clip are provided with apertures 12 which render said arms more resilient at the point where they cross the space intervening between the wings 3 of the clamp members, and thus said arms 10 may be said to break joint with the clamp members, and said clip arms, taken in connection with the clamp members, provide a continuous hearing all around the joint. By reason of the particular shape and disposition of the arms of the clip, it will be understood that as the clamp members are drawn toward each other. they act upon the arms of the clip to crowd the same inward and make them conform to the outer contour of the hose, thus crowding said hose firmly against and. around the pipe or nozzle within the same. A liquid-tight joint is thus obtained between the hose and. the pipe or nozzle with which it is connected.

Ilaving thus described the invention, we claim as new:

1. The herein described hose-clamp comprising oppositely arranged still clamp members having substantially semi-cirmilar body portions, means for drawing said clamp members toward each other, and a spring clip connected to one of said members and comprising arms which together exceed a semi-circle, said arms being adapted to embrace and hold the hose sections l'ri'ctionally, for the purpose described.

2. The herein described clamp comprising oppositely arranged members l'iaving substantially semi-circular body portions, means lor drawing said clamp members toward each other, and a spring-clip carried by one of said. members and comprising apcrtured spring arms with inbent extremities, said clip as a whole exceeding a semi-circle, and said arms being adapted to embrace and hold, the hose sections lrictionally, for the purpose described.

In testimony whereof, we allix our signatures in presence of two witnesses.
